Video Call Interface Dynamic Window Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video call technologies face challenges in efficiently managing multiple channels, leading to limitations in displaying video and voice windows, particularly when the number of participants exceeds the preset channel capacity, resulting in suboptimal user experience.
Innovation Solution
A display apparatus and method that dynamically adjust the video call interface by dividing it into two areas, where the first area displays a preset number of video windows and the second area displays the remaining participants' audio-only, allowing seamless switching between video and voice modes based on the number of current call channels, ensuring all participants can either view or hear each other without exceeding the device's processing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the number of video windows is increased to accommodate more participants, then the completeness of video information is improved, but the device processing capacity is exceeded
Solution Approach 1:
The call participants are segmented into two groups: video participants and audio participants. The display interface is divided into a first area for video windows and a second area for audio windows. This segmentation allows the system to handle more total participants by selectively rendering video and audio streams to different groups, reducing the processing load on the device while maintaining information completeness across all participants.
2Adaptability or versatility
If the number of display windows is increased to show all participants, then the user experience is improved, but the interface complexity increases
Solution Approach 1:
Different areas of the interface are assigned different qualities and functions: the first area displays video windows with visual information, while the second area displays audio windows with audio-only information. This local differentiation allows the interface to accommodate more participants without uniformly increasing complexity across the entire display, as each area has a specialized purpose and layout.
3Reliability
If video windows are displayed for all participants, then the video call quality is improved, but the energy consumption increases
Solution Approach 1:
The system dynamically adjusts the number of video windows based on the total number of participants. When participants exceed a threshold, the system automatically converts some video windows to audio windows. This dynamic adaptation allows the system to maintain high video call quality for essential participants while reducing energy consumption by eliminating redundant video rendering for excessive participants.

AI summary
Provided are a video call method and a display apparatus. The display apparatus includes: a display, an audio player, a communicator, a user input interface, and a controller. The controller is configured to: control the display to present a first area and a second area on a call interface for a video call, where the first area is for presenting one or more video chatting windows, and the second area is for presenting one or more voice chatting windows; obtain a quantity Y for indicating number of parties currently participating in the video call from the sever; and in response to the quantity Y being greater than a preset quantity X of channels that the display apparatus is able to support, control the display to present X video chatting windows in the first area, and control the display to present (Y-X) voice chatting windows in the second area.
